Kiddinglife opened a new issue #7955: About the performance of select * from xxx limit 1
URL: https://github.com/apache/incubator-druid/issues/7955
 
 
   Hi folks,
   
   I did select * from xxx limit 1 in single-instance influxdb in prod and it crashes due to increditable amounts of memory and cpu comsumptions.... very slow... Now I am seeking the replacement of it and clickhouse looks like a good replacement of influxdb.
   
   I checked the documentation that says the query results will be based on sort key. I am wondering about the performances of clickhouse on select * from xxx limit 1.
   
   Thanks.
